Description

Technical Field

[0001] The utility model relates to the field of wood processing equipment technology, in particular to a thin plate numerical control cutting machine. Background Art

[0002] With the continuous development of the home improvement industry, more and more people choose to customize furniture when decorating their houses. Customized furniture is produced and processed in furniture factories and then assembled on site. During the production process, CNC cutting machines are required to cut the original top material panels.

[0003] In the prior art, when using a CNC cutting machine to process a plate, its operation is relatively simple and its precision is high, which brings great convenience to personnel when processing the plate. At present, when the existing CNC cutting machine processes the plate, the dust on the plate will adhere to the CNC cutting machine, and the plate debris will also fall on the CNC cutting machine, which will make the surface of the CNC cutting machine relatively dirty, and most of the existing CNC cutting machines are not equipped with a dust suction device, so it is not convenient for personnel to clean the dust and plate debris on the CNC cutting machine in time.

[0004] Later, a dust suction device for CNC cutting machines appeared on the market, such as CN217254876U, which includes a CNC cutting machine body and a dust removal mechanism; the dust removal mechanism is arranged on both sides of the CNC cutting machine body; by setting the dust removal mechanism, after processing the plate, the personnel need to pull the magnetic bent pipe out of the telescopic slot, thereby pulling the dust removal cylinder out of the two sides of the CNC cutting machine body, adjust the length of the magnetic bent pipe extending from the telescopic slot, and then move the lifting pipe upward to adjust the height of the dust removal cylinder, and then start the dust removal motor in the dust removal cylinder, and use the dust suction holes on the connecting plate to absorb the dust on the CNC cutting machine body and the debris of the plate, so as to facilitate the personnel to promptly remove the dust and the debris of the plate on the CNC cutting machine after processing the plate. This dust suction device for CNC cutting machines has the following defects: it needs to wait for After the plate processing is completed, when the dust removal mechanism on both sides of the CNC cutting machine body is manually taken to adjust the height of the dust removal cylinder for dust collection, the process is relatively numerous and complicated, especially the link of inserting the terminal into the plastic part, there are defects such as low dust removal efficiency, large human resource consumption, and high labor intensity of the operators; and the layout of this dust collection device causes the CNC cutting machine to occupy a large space, affecting the subsequent placement of the workshop; and when this CNC cutting machine uses a dust collection device to process the plate, the dust and plate debris generated will spread with the flow of air, which will cause the dust and plate debris generated during processing to be blown on the workshop floor or dispersed in the air, and the dust and plate debris blown to the ground will need to be dusted and cleaned later. In addition, long-term manual absorption of dust will affect their physical and mental health.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content
